“以实验为基础”是化学学科的基本特征,化学学习离不开实验。基础教育化学新课程改革强调创设生动而有意义的学习情境,倡导以科学探究为主的多样化学习方式,重视学生的亲身经历和体验。一、实验思想的渗透化学性质的教学往往可通过实验向学生提供足够的感性材料。但是这并不意味着要穷尽所有事例。值得注意的是,某一化学性质涉及的大量事例中,有的本质特征明显,而有的非本质联系强烈,我们必须精选那些最能反映本质特征的例子, “Based on experiment ” is the basic characteristic of chemical discipline, chemical study can not be separated from experiment. Basic Education Chemistry The new curriculum reform emphasizes the creation of vivid and meaningful learning situations, advocating a diversified learning style based on scientific inquiry, and attaching importance to students’ personal experiences and experiences. First, the infiltration of experimental thinking Chemical teaching can often provide enough perceptual material to students through experiments. But this does not mean exhaustive. It is worth noting that some of the large number of cases involving a chemical nature have obvious essential features and some are of a very non-essential nature. We must select examples that best reflect the essential characteristics,
